Why won't my PC start?

Question

Windows

At startup , the bluetooth keyboard hangs in the picture. Can't get into bios on startup. The picture del, f9, f12, end appears. I understand this is a presentation of the motherboard. As a rare animal that is still using wine, I ask you to put me in the Red Book and save me. There is a wired one, but it does not respond to it either. Which button should be pressed to start the last successful start of Windows or without drivers? Dust blew. Pulled out the wires and put them in. This picture turns off from time to time and after 5 seconds of a black screen appears again. As if the system is trying to start but something is preventing it.
